EAR-MUFFLER.

Application iled Setobei' 5, 1969.

To @ZZ whom it 'may concern.'

Be it known that E, Uiiliniins J. KELLER, a citizen ot the UnitedStates, residing at Bloomsburg, in the county ot Columbia and State ot'Pennsylvania, have invented eertain new and useful l'inproveinents inFlan uftlcrs; and l do hereby declare the following' to be a. full,clear, and exact` description oi the invention, such as will enableothers skilled in the art to which it appertains to inalie and use thesaine.

My invention relates to new and useful improvements in ear inutllers,and is niore )liarticularly an improvement over iny tornier patent lo.804.731, dated Nov. lit, 1905, and iny object, is to provide ineans torattaching a wire to a circular body and arranging the ire whereby thesaine will direct an inward tension on the inuiilers proper, and afurther objectis to so arrange the wire that when not in use, the partswill be assembled in coinpact torni.

@ther objects and advantages will be hereinafter referred to and inorcparticularly pointed out in the claiin.

ln the accompanying drawings torn'iing part of this application, Figurel is an elevation partly in section ot the inulllei's ready to beapplied to use. tion thei'eet' partly in section. F ig. 3 is an endelevation partly in section showing the parts oil the niutller i'oldedtogether. ig. d is an edge elevation tliereoi partly in section, an l,Fig. is a detail elevation oi" ay portion oit the inutller traineshowing the inanner ot attaching the wire thereto.

Referring to the drawings in which siniilar reference nunieralsdesignate corresponding parts throughout the several views, l indicatesthe traine adapted to support the niul'llers, which are coinposed ofcloth or like substance, said traines being two in ninnber and coniposedof liat rings of inetal, one portion of the tranies l having integralears 3 at the inner and outer edges of the traine, through which extendthe ends of a wire and in order to hold the wire in engagement with saidrings and at the saine tinie perinit rotation oiC the rings on the wire,that portion ot' the wire between the two ears is Fig. 2 an endelevarateiited hier. 25,5, it. Serial Io. 521,123.

itlattened as shown at 5, the flattening ot' said wire in one directioncausing the saine to bulge iii the opposite direction, thus toria ing anenlarged portion which will prevent the wire i'ironi moving lengthwisethrough the ears, the flattened portion being lornied atter the wire hasbeen introduced through the ears.

The wire si. is ornied of spring nietal and is so arranged that when theiiiutliers proper are folded together as shown in Fig. said wire will besubstantially circular and the iiiufliers will register with each other,thereby reducing the device to a conipaet torni and likewise when theniul'llers are separated and placed in position over the ears, the tension of the wire 4 will be increased and serve to hold the niulllerssecurely in position over the ears.

Ey arranging the wire L whereby the tension thereof will cause the saineto assume a circular position as shown in Fig. 3 and register theinulllers proper with cach other. it will likewise serve to direct equalinward pressure on the inulilers said inufllcrs are placed at rightangles to the positions shown in Fig. 3 when the inutllers are appliedto use and it will further be seen that in view of the curvature ot' thewire, it will snugly iit around the back portion ot the head oi' neck ofthe wearer.

'ilhat l claini is:

EL device of the class described, coniprising a pair of traines, a wireeffecting connection between said trames, each traine having its formingineinbcr provided with opposed ears at the lateral edges of saidtorining nieinber, said connecting wire having' its ends flattenedbetween said ears, said wires being oil spiral outline and adapted toallow said frames to be arranged parallel with each other.

in testinioiiy whereof I have signed iny naine to this speciiication inthe presence ot two subscribing witnesse.
